Shape Transformation of Wave Beams Falling on Quasiperiodic Media
Bragg structures with distortion of periodicity is considered. Effects of scattering the wave beams falling at oblique angles are theoretically investigated. Methods of characteristic matrices and plane-wave decomposition are used for obtaining angular and spatial distribution of reflected and transmitted wave beams. Magnitudes and phases of scattered fields are analysed. Phenomena of anomalous behaviour of group shifts (decreasing and negative ones) are observed for Bragg structures with different type of distortions
